I have shot our first inhouse corporate video and the faces are way overexposed. There is not enough detail in the image to color correct it properly, plus with the amount of videos we need to produce in such a short period of time, I'd like to minimize the amount of color correction we have to do in post. So, how should I be lighting the subjects to avoid overexposed faces? I have 4 lights, and can put up to a max of 500 watt bulbs on two of them, and a max of 150 watts on the other 2. Our studio is 12 ft wide and I have the lights as far as they can go on either side of the subject against the wall.
